Marketplace for AI tools & prompts: buy & sell AI building blocks

A marketplace for AI tools and prompts connects two sides: people looking for a ready-made AI solution – and people who have already built exactly that. Instead of starting from scratch, you buy a finished base recipe and turn it into your own dish with AI. That's the idea behind Grammai.

What is an AI marketplace?

An AI marketplace is a platform where digital AI products are traded: prompts, templates, automations and complete AI building blocks. Buyers save time because they get a proven base. Sellers earn money with knowledge they already have.

The difference from a classic app store: you don't buy closed software, but an adaptable base. Use it right away – or tailor it to your case with an AI chat like ChatGPT.

What you can buy on Grammai

• Prompts – well-crafted instructions for ChatGPT & co. that reliably work.
• AI building blocks & templates – e.g. a time tracking sheet, shift plans, inventory or sales tools.
• Solutions by area – from Business and Marketing to Organization and Family.

Every product shows you difficulty level, use case, required tools and a demo preview in advance. So you know what you get before you buy.

How buying works

1. Browse the home page or the search – simply describe your problem.
2. Open a product and check description, reviews and the free demo.
3. Pay securely via PayPal or card. The full step-by-step guide then appears in your library.

Important: digital products on Grammai are not downloaded as a file, but shown in a protected online view with a personal watermark. This protects the sellers' work – more in our guidelines.

Selling yourself: turn knowledge into income

Got good prompts or templates yourself? Become a seller. You keep 60% per sale, the platform takes 40%. The path:

1. Register as a seller and verify briefly.
2. Create a product: title, category, price and a clear step-by-step guide.
3. After the team's review, your product goes live.

Who is an AI marketplace for?

For anyone who wants a quick result instead of a long learning curve: freelancers, small businesses, creatives, families – private and commercial. You don't need programming skills. The base is ready; the rest is you.
